Re: 48G vs 49G+ User RPL Speed Comparison Message #6 Posted by Kiyoshi Akima on 16 Nov 2013, 9:24 p.m., in response to message #1 by John Colvin
I don't have a 49 but my understanding is that the 50g is more-or-less the same hardware so I tried this on the 50g. It's also my understanding that in general the ARM emulating a Saturn is faster than the Saturn. But I've been known to be wrong...
With both Numeric and Approx checked, my UserRPL program approximated 250! as 3.2E492 in about 0.8 seconds. With both Numeric and Approx unchecked, the program generated a 493-digit integer in about 5.1 seconds.
My 48SX approximated it in about 19000 ticks while my 48GX did it in about 13000 ticks (2.3 and 1.6 seconds).
Here's the program I used:
<<
1. DUP ROT FOR I
I *
NEXT
>>
For exact mode, remove the decimal point.
